Solved Example on Polygon
Ques: Identify the set hat shows the polygons arranged in the decreasing order of number of sides.
Choices:
A. Octagon, hexagon, pentagon, and quadrilateral
B. Pentagon, hexagon, octagon, and quadrilateral
C. Quadrilateral, pentagon, hexagon, and octagon
D. Hexagon, pentagon, quadrilateral, and octagon
Correct Answer: A
Solution:
Step 1: The number of sides of quadrilateral, hexagon, pentagon, and octagon are 4, 6, 5 and 8 respectively.
